夷、夏观念源远流长,夷夏之别观念的基本内涵奠定于春秋战国时期,而后深化出大一统,王者无外和以夏变夷等新思想。夷夏之别主旨是区别华夏族与周边诸族。在漫长的历史演变中,夷夏之别的衡量标准也由血统、地域、习性等的自然习俗论,发展为政治文化论。虽然几种标准因时因地不断重提与实践,但政治文化论始终占据着主导地位。 The concept of the barbarians and the summer is well established. The basic connotation of the notion of barbarians and lakes was laid in the Spring and Autumn Period and the Warring States Period, and then deepened into new ideas such as unification of the monarchy, the absence of the outside and the change of the summer. The theme of Yi Xia is to distinguish the Huaxia ethnic group from the surrounding ethnic groups. In the long history of evolution, the other measure of Yi Xia also developed from the natural custom of descent, region and habit to political culture. Although several standards have been constantly revisited and practiced due to local conditions, the political culture theory has always dominated.
